Abstract: An electro-hydraulic clutch system for a motor vehicle includes a clutch mechanism that selectively engages an engine of the motor vehicle with a gear box, an actuator that pumps and retrieves hydraulic fluid to and from the clutch mechanism to activate the clutch mechanism, and a solenoid with a valve and/or a check ball that is disposed in the path of the hydraulic fluid between the actuator and the clutch mechanism. The solenoid has a normally closed position to prevent flow of the hydraulic fluid back to the actuator in the event of a system failure. The solenoid can also be used to reduce energy consumption in steady state conditions.

Abstract: A shifting device is provided for the gear selection in a manual transmission that includes, but is not limited to a shift/selector lever that can be moved in a shifting degree of freedom and a selection degree of freedom, a measuring sensor for measuring a current position (s, w) of the shift/selector lever in the two degrees of freedom, a two-dimensionally controllable actuator device and a control circuit for the controlling of the actuator device in a position (S, W) which is associated with the sensed position (s, w) of the shift/selector lever, which depicts the movement region of the shift/selector lever on a region of possible positions of the actuator device. The movement region of the shift/selector lever included, but is not limited to a two-dimensional prohibited part region, in which the shift/selector lever is simultaneously moveable in both degrees of freedom.

Abstract: An external gear shift for the gear selection in a manual transmission is provided that includes, but is not limited to a gearshift/selector lever, which is guided in a link plate and which is movable along a selector track and a plurality of shifting tracks, and a measuring sensor to detect an instantaneous position (s, w) of the gearshift/selector lever. Guide fingers of the link plate disposed between shifting and selector tracks each have flanks oriented obliquely to the shifting and selector tracks.
